Barman News - History of user-visible changes
Version 3.3.0 - 14 December 2022
- A backup can now be given a name at backup time using the new
`--name` option supported by the `barman backup` and
`barman-cloud-backup` commands. The backup name can then be used
in place of the backup ID when running commands to interact with
backups. Additionally, the commands to list and show backups have
been been updated to include the backup name in the plain text and
JSON output formats.
- Stricter checking of PostgreSQL version to verify that Barman is
running against a supported version of PostgreSQL.
- Bug fixes:
- Fix inconsistencies between the barman cloud command docs and
the help output for those commands.
- Use a new PostgreSQL connection when switching WALs on the
primary during the backup of a standby to avoid undefined
behaviour such as `SSL error` messages and failed connections.
- Reduce log volume by changing the default log level of stdout
for commands executed in child processes to `DEBUG` (with the
exception of `pg_basebackup` which is deliberately logged at
`INFO` level due to it being a long-running process where it is
frequently useful to see the output during the execution of the
command).
Version 3.2.0 - 20 October 2022
- `barman-cloud-backup-delete` now accepts a `--batch-size` option
which determines the maximum number of objects deleted in a single
request.
- All `barman-cloud-*` commands now accept a `--read-timeout` option
which, when used with the `aws-s3` cloud provider, determines the
read timeout used by the boto3 library when making requests to S3.
- Bug fixes:
- Fix the failure of `barman recover` in cases where
`backup_compression` is set in the Barman configuration but the
PostgreSQL server is unavailable.
Version 3.1.0 - 14 September 2022
- Backups taken with `backup_method = postgres` can now be compressed
using lz4 and zstd compression by setting `backup_compression = lz4`
or `backup_compression = zstd` respectively. These options are only
supported with PostgreSQL 15 (beta) or later.
- A new option `backup_compression_workers` is available which sets
the number of threads used for parallel compression. This is
currently only available with `backup_method = postgres` and
`backup_compression = zstd`.
- A new option `primary_conninfo` can be set to avoid the need for
backups of standbys to wait for a WAL switch to occur on the primary
when finalizing the backup. Barman will use the connection string
in `primary_conninfo` to perform WAL switches on the primary when
stopping the backup.
- Support for certain Rsync versions patched for CVE-2022-29154 which
require a trailing newline in the `--files-from` argument.
- Allow `barman receive-wal` maintenance options (`--stop`, `--reset`,
`--drop-slot` and `--create-slot`) to run against inactive servers.
- Add `--port` option to `barman-wal-archive` and `barman-wal-restore`
commands so that a custom SSH port can be used without requiring any
SSH configuration.
- Various documentation improvements.
- Python 3.5 is no longer supported.
- Bug fixes:
- Ensure PostgreSQL connections are closed cleanly during the
execution of `barman cron`.
- `barman generate-manifest` now treats pre-existing
backup_manifest files as an error condition.
- backup_manifest files are renamed by appending the backup ID
during recovery operations to prevent future backups including
an old backup_manifest file.
- Fix epoch timestamps in json output which were not
timezone-aware.
- The output of `pg_basebackup` is now written to the Barman
log file while the backup is in progress.
- We thank barthisrael, elhananjair, kraynopp, lucianobotti, and mxey
for their contributions to this release.
Version 3.0.1 - 27 June 2022
- Bug fixes:
- Fix package signing issue in PyPI (same sources as 3.0.0)
Version 3.0.0 - 23 June 2022
- BREAKING CHANGE: PostgreSQL versions 9.6 and earlier are no longer
supported. If you are using one of these versions you will need to
use an earlier version of Barman.
- BREAKING CHANGE: The default backup mode for Rsync backups is now
concurrent rather than exclusive. Exclusive backups have been
deprecated since PostgreSQL 9.6 and have been removed in PostgreSQL
15. If you are running Barman against PostgreSQL versions earlier
than 15 and want to use exclusive backups you will now need to set
`exclusive_backup` in `backup_options`.
- BREAKING CHANGE: The backup metadata stored in the `backup.info` file
for each backup has an extra field. This means that earlier versions
of Barman will not work in the presence of any backups taken with
3.0.0. Additionally, users of pg-backup-api will need to upgrade it
to version 0.2.0 so that pg-backup-api can work with the updated
metadata.
- Backups taken with `backup_method = postgres` can now be compressed
by pg_basebackup by setting the `backup_compression` config option.
Additional options are provided to control the compression level,
the backup format and whether the pg_basebackup client or the
PostgreSQL server applies the compression. NOTE: Recovery of these
backups requires Barman to stage the compressed files on the recovery
server in a location specified by the `recovery_staging_path` option.
- Add support for PostgreSQL 15. Exclusive backups are not supported
by PostgreSQL 15 therefore Barman configurations for PostgreSQL 15
servers are not allowed to specify `exclusive_backup` in
`backup_options`.
- Various documentation improvements.
- Use custom_compression_magic, if set, when identifying compressed
WAL files. This allows Barman to correctly identify uncompressed
WALs (such as `*.partial` files in the `streaming` directory) and
return them instead of attempting to decompress them.
- Bug fixes:
- Fix an ordering bug which caused Barman to log the message
"Backup failed issuing start backup command." while handling a
failure in the stop backup command.
- Fix a bug which prevented recovery using `--target-tli` when
timelines greater than 9 were present, due to hexadecimal values
from WAL segment names being parsed as base 10 integers.
- Fix an import error which occurs when using barman cloud with
certain python2 installations due to issues with the enum34
dependency.
- Fix a bug where Barman would not read more than three bytes from
a compressed WAL when attempting to identify the magic bytes. This
means that any custom compressed WALs using magic longer than three
bytes are now decompressed correctly.
- Fix a bug which caused the `--immediate-checkpoint` flag to be
ignored during backups with `backup_method = rsync`.
Version 2.19 - 9 March 2022
- Change `barman diagnose` output date format to ISO8601.
- Add Google Cloud Storage (GCS) support to barman cloud.
- Support `current` and `latest` recovery targets for the `--target-tli`
option of `barman recover`.
- Add documentation for installation on SLES.
- Bug fixes:
- `barman-wal-archive --test` now returns a non-zero exit code when
an error occurs.
- Fix `barman-cloud-check-wal-archive` behaviour when `-t` option is
used so that it exits after connectivity test.
- `barman recover` now continues when `--no-get-wal` is used and
`"get-wal"` is not set in `recovery_options`.
- Fix `barman show-servers --format=json ${server}` output for
inactive server.
- Check for presence of `barman_home` in configuration file.
- Passive barman servers will no longer store two copies of the
tablespace data when syncing backups taken with
`backup_method = postgres`.
- We thank richyen for his contributions to this release.
Version 2.18 - 21 January 2022
- Add snappy compression algorithm support in barman cloud (requires the
optional python-snappy dependency).
- Allow Azure client concurrency parameters to be set when uploading
WALs with barman-cloud-wal-archive.
- Add `--tags` option in barman cloud so that backup files and archived
WALs can be tagged in cloud storage (aws and azure).
- Update the barman cloud exit status codes so that there is a dedicated
code (2) for connectivity errors.
- Add the commands `barman verify-backup` and `barman generate-manifest`
to check if a backup is valid.
- Add support for Azure Managed Identity auth in barman cloud which can
be enabled with the `--credential` option.
- Bug fixes:
- Change `barman-cloud-check-wal-archive` behavior when bucket does
not exist.
- Ensure `list-files` output is always sorted regardless of the
underlying filesystem.
- Man pages for barman-cloud-backup-keep, barman-cloud-backup-delete
and barman-cloud-check-wal-archive added to Python packaging.
- We thank richyen and stratakis for their contributions to this
release.
Version 2.17 - 1 December 2021
- Bug fixes:
- Resolves a performance regression introduced in version 2.14 which
increased copy times for `barman backup` or `barman recover` commands
when using the `--jobs` flag.
- Ignore rsync partial transfer errors for `sender` processes so that
such errors do not cause the backup to fail (thanks to barthisrael).
Version 2.16 - 17 November 2021
- Add the commands `barman-check-wal-archive` and `barman-cloud-check-wal-archive`
to validate if a proposed archive location is safe to use for a new PostgreSQL
server.
- Allow Barman to identify WAL that's already compressed using a custom
compression scheme to avoid compressing it again.
- Add `last_backup_minimum_size` and `last_wal_maximum_age` options to
`barman check`.
- Bug fixes:
- Use argparse for command line parsing instead of the unmaintained
argh module.
- Make timezones consistent for `begin_time` and `end_time`.
- We thank chtitux, George Hansper, stratakis, Thoro, and vrms for their
contributions to this release.
Version 2.15 - 12 October 2021
- Add plural forms for the `list-backup`, `list-server` and
`show-server` commands which are now `list-backups`, `list-servers`
and `show-servers`. The singular forms are retained for backward
compatibility.
- Add the `last-failed` backup shortcut which references the newest
failed backup in the catalog so that you can do:
- `barman delete <SERVER> last-failed`
- Bug fixes:
- Tablespaces will no longer be omitted from backups of EPAS
versions 9.6 and 10 due to an issue detecting the correct version
string on older versions of EPAS.
Version 2.14 - 22 September 2021
- Add the `barman-cloud-backup-delete` command which allows backups in
cloud storage to be deleted by specifying either a backup ID or a
retention policy.
- Allow backups to be retained beyond any retention policies in force by
introducing the ability to tag existing backups as archival backups
using `barman keep` and `barman-cloud-backup-keep`.
- Allow the use of SAS authentication tokens created at the restricted
blob container level (instead of the wider storage account level) for
Azure blob storage
- Significantly speed up `barman restore` into an empty directory for
backups that contain hundreds of thousands of files.
- Bug fixes:
- The backup privileges check will no longer fail if the user lacks
"userepl" permissions and will return better error messages if any
required permissions are missing (#318 and #319).
Version 2.13 - 26 July 2021
- Add Azure blob storage support to barman-cloud
- Support tablespace remapping in barman-cloud-restore via
`--tablespace name:location`
- Allow barman-cloud-backup and barman-cloud-wal-archive to run as
Barman hook scripts, to allow data to be relayed to cloud storage
from the Barman server
- Bug fixes:
- Stop backups failing due to idle_in_transaction_session_timeout
(https://github.com/EnterpriseDB/barman/issues/333)
- Fix a race condition between backup and archive-wal in updating
xlog.db entries (#328)
- Handle PGDATA being a symlink in barman-cloud-backup, which led to
"seeking backwards is not allowed" errors on restore (#351)
- Recreate pg_wal on restore if the original was a symlink (#327)
- Recreate pg_tblspc symlinks for tablespaces on restore (#343)
- Make barman-cloud-backup-list skip backups it cannot read, e.g.,
because they are in Glacier storage (#332)
- Add `-d database` option to barman-cloud-backup to specify which
database to connect to initially (#307)
- Fix "Backup failed uploading data" errors from barman-cloud-backup
on Python 3.8 and above, caused by attempting to pickle the boto3
client (#361)
- Correctly enable server-side encryption in S3 for buckets that do
not have encryption enabled by default.
In Barman 2.12, barman-cloud-backup's `--encryption` option did
not correctly enable encryption for the contents of the backup if
the backup was stored in an S3 bucket that did not have encryption
enabled. If this is the case for you, please consider deleting
your old backups and taking new backups with Barman 2.13.
If your S3 buckets already have encryption enabled by default
(which we recommend), this does not affect you.
Version 2.12.1 - 30 June 2021
- Bug fixes:
- Allow specifying target-tli with other target-* recovery options
- Fix incorrect NAME in barman-cloud-backup-list manpage
- Don't raise an error if SIGALRM is ignored
- Fetch wal_keep_size, not wal_keep_segments, from Postgres 13
Version 2.12 - 5 Nov 2020
- Introduce a new backup_method option called local-rsync which
targets those cases where Barman is installed on the same server
where PostgreSQL is and directly uses rsync to take base backups,
bypassing the SSH layer.
- Bug fixes:
- Avoid corrupting boto connection in worker processes
- Avoid connection attempts to PostgreSQL during tests
Version 2.11 - 9 Jul 2020
- Introduction of the barman-cli-cloud package that contains all cloud
related utilities.
- Add barman-cloud-wal-restore to restore a WAL file previously
archived with barman-cloud-wal-archive from an object store
- Add barman-cloud-restore to restore a backup previously taken with
barman-cloud-backup from an object store
- Add barman-cloud-backup-list to list backups taken with
barman-cloud-backup in an object store
- Add support for arbitrary archive size for barman-cloud-backup
- Add support for --endpoint-url option to cloud utilities
- Remove strict superuser requirement for PG 10+ (by Kaarel Moppel)
- Add --log-level runtime option for barman to override default log
level for a specific command
- Support for PostgreSQL 13
- Bug fixes:
- Suppress messages and warning with SSH connections in barman-cli
(GH-257)
- Fix a race condition when retrieving uploaded parts in
barman-cloud-backup (GH-259)
- Close the PostgreSQL connection after a backup (GH-258)
- Check for uninitialized replication slots in receive-wal --reset
(GH-260)
- Ensure that begin_wal is valorised before acting on it (GH-262)
- Fix bug in XLOG/WAL arithmetic with custom segment size (GH-287)
- Fix rsync compatibility error with recent rsync
- Fix PostgreSQLClient version parsing
- Fix PostgreSQL exception handling with non ASCII messages
- Ensure each postgres connection has an empty search_path
- Avoid connecting to PostgreSQL while reading a backup.info file
If you are using already barman-cloud-wal-archive or barman-cloud-backup
installed via RPM/Apt package and you are upgrading your system, you
must install the barman-cli-cloud package. All cloud related tools are
now part of the barman-cli-cloud package, including
barman-cloud-wal-archive and barman-cloud-backup that were previously
shipped with barman-cli. The reason is complex dependency management of
the boto3 library, which is a requirement for the cloud utilities.
Version 2.10 - 5 Dec 2019
- Pull .partial WAL files with get-wal and barman-wal-restore,
allowing restore_command in a recovery scenario to fetch a partial
WAL file's content from the Barman server. This feature simplifies
and enhances RPO=0 recovery operations.
- Store the PostgreSQL system identifier in the server directory and
inside the backup information file. Improve check command to verify
the consistency of the system identifier with active connections
(standard and replication) and data on disk.
- A new script called barman-cloud-wal-archive has been added to the
barman-cli package to directly ship WAL files from PostgreSQL (using
archive_command) to cloud object storage services that are
compatible with AWS S3. It supports encryption and compression.
- A new script called barman-cloud-backup has been added to the
barman-cli package to directly ship base backups from a local
PostgreSQL server to cloud object storage services that are
compatible with AWS S3. It supports encryption, parallel upload,
compression.
- Automated creation of replication slots through the server/global
option create_slot. When set to auto, Barman creates the replication
slot, in case streaming_archiver is enabled and slot_name is
defined. The default value is manual for back-compatibility.
- Add '-w/--wait' option to backup command, making Barman wait for all
required WAL files to be archived before considering the backup
completed. Add also the --wait-timeout option (default 0, no
timeout).
- Redact passwords from Barman output, in particular from
barman diagnose (InfoSec)
- Improve robustness of receive-wal --reset command, by verifying that
the last partial file is aligned with the current location or, if
present, with replication slot's.
- Documentation improvements
- Bug fixes:
- Wrong string matching operation when excluding tablespaces
inside PGDATA (GH-245)
- Minor fixes in WAL delete hook scripts (GH-240)
- Fix PostgreSQL connection aliveness check (GH-239)
Version 2.9 - 1 Aug 2019
- Transparently support PostgreSQL 12, by supporting the new way of
managing recovery and standby settings through GUC options and
signal files (recovery.signal and standby.signal)
- Add --bwlimit command line option to set bandwidth limitation for
backup and recover commands
- Ignore WAL archive failure for check command in case the latest
backup is WAITING_FOR_WALS
- Add --target-lsn option to set recovery target Log Sequence Number
for recover command with PostgreSQL 10 or higher
- Add --spool-dir option to barman-wal-restore so that users can
change the spool directory location from the default, avoiding
conflicts in case of multiple PostgreSQL instances on the same
server (thanks to Drazen Kacar).
- Rename barman_xlog directory to barman_wal
- JSON output writer to export command output as JSON objects and
facilitate integration with external tools and systems (thanks to
Marcin Onufry Hlybin). Experimental in this release.
Bug fixes:
- replication-status doesn’t show streamers with no slot (GH-222)
- When checking that a connection is alive (“SELECT 1” query),
preserve the status of the PostgreSQL connection (GH-149). This
fixes those cases of connections that were terminated due to
idle-in-transaction timeout, causing concurrent backups to fail.
Version 2.8 - 17 May 2019
- Add support for reuse_backup in geo-redundancy for incremental
backup copy in passive nodes
- Improve performance of rsync based copy by using strptime instead of
the more generic dateutil.parser (#210)
- Add ‘--test’ option to barman-wal-archive and barman-wal-restore to
verify the connection with the Barman server
- Complain if backup_options is not explicitly set, as the future
default value will change from exclusive_backup to concurrent_backup
when PostgreSQL 9.5 will be declared EOL by the PGDG
- Display additional settings in the show-server and diagnose
commands: archive_timeout, data_checksums, hot_standby,
max_wal_senders, max_replication_slots and wal_compression.
- Merge the barman-cli project in Barman
- Bug fixes:
- Fix encoding error in get-wal on Python 3 (Jeff Janes, #221)
- Fix exclude_and_protect_filter (Jeff Janes, #217)
- Remove spurious message when resetting WAL (Jeff Janes, #215)
- Fix sync-wals error if primary has WALs older than the first
backup
- Support for double quotes in synchronous_standby_names setting
- Minor changes:
- Improve messaging of check --nagios for inactive servers
- Log remote SSH command with recover command
- Hide logical decoding connections in replication-status command
This release officially supports Python 3 and deprecates Python 2 (which
might be discontinued in future releases).
PostgreSQL 9.3 and older is deprecated from this release of Barman.
Support for backup from standby is now limited to PostgreSQL 9.4 or
higher and to WAL shipping from the standby (please refer to the
documentation for details).
Version 2.7 - 21 Mar 2019
- Fix error handling during the parallel backup. Previously an
unrecoverable error during the copy could have corrupted the barman
internal state, requiring a manual kill of barman process with
SIGTERM and a manual cleanup of the running backup in PostgreSQL.
(GH#199)
- Fix support of UTF-8 characters in input and output (GH#194 and
GH#196)
- Ignore history/backup/partial files for first sync of geo-redundancy
(GH#198)
- Fix network failure with geo-redundancy causing cron to break
(GH#202)
- Fix backup validation in PostgreSQL older than 9.2
- Various documentation fixes
Version 2.6 - 4 Feb 2019
- Add support for Geographical redundancy, introducing 3 new commands:
sync-info, sync-backup and sync-wals. Geo-redundancy allows a Barman
server to use another Barman server as data source instead of a
PostgreSQL server.
- Add put-wal command that allows Barman to safely receive WAL files
via PostgreSQL's archive_command using the barman-wal-archive script
included in barman-cli
- Add ANSI colour support to check command
- Minor fixes:
- Fix switch-wal on standby with an empty WAL directory
- Honour archiver locking in wait_for_wal method
- Fix WAL compression detection algorithm
- Fix current_action in concurrent stop backup errors
- Do not treat lock file busy as an error when validating a backup
Version 2.5 - 23 Oct 2018
- Add support for PostgreSQL 11
- Add check-backup command to verify that WAL files required for
consistency of a base backup are present in the archive. Barman now
adds a new state (WAITING_FOR_WALS) after completing a base backup,
and sets it to DONE once it has verified that all WAL files from
start to the end of the backup exist. This command is included in
the regular cron maintenance job. Barman now notifies users
attempting to recover a backup that is in WAITING_FOR_WALS state.
- Allow switch-xlog --archive to work on a standby (just for the
archive part)
- Bug fixes:
- Fix decoding errors reading external commands output (issue
#174)
- Fix documentation regarding WAL streaming and backup from
standby
Version 2.4 - 25 May 2018
- Add standard and retry hook scripts for backup deletion (pre/post)
- Add standard and retry hook scripts for recovery (pre/post)
- Add standard and retry hook scripts for WAL deletion (pre/post)
- Add --standby-mode option to barman recover to add standby_mode = on
in pre-generated recovery.conf
- Add --target-action option to barman recover, allowing users to add
shutdown, pause or promote to the pre-generated recovery.conf file
- Improve usability of point-in-time recovery with consistency checks
(e.g. recovery time is after end time of backup)
- Minor documentation improvements
- Drop support for Python 3.3
Relevant bug fixes:
- Fix remote get_file_content method (GitHub #151), preventing
incremental recovery from happening
- Unicode issues with command (GitHub #143 and #150)
- Add --wal-method=none when pg_basebackup >= 10 (GitHub #133)
Minor bug fixes:
- Stop process manager module from overwriting lock files content
- Relax the rules for rsync output parsing
- Ignore vanished files in streaming directory
- Case insensitive slot names (GitHub #170)
- Make DataTransferFailure.from_command_error() more resilient
(GitHub #86)
- Rename command() to barman_command() (GitHub #118)
- Initialise synchronous standby names list if not set (GitHub #111)
- Correct placeholders ordering (GitHub #138)
- Force datestyle to iso for replication connections
- Returns error if delete command does not remove the backup
- Fix exception when calling is_power_of_two(None)
- Downgraded sync standby names messages to debug (GitHub #89)
Version 2.3 - 5 Sep 2017
- Add support to PostgreSQL 10
- Follow naming changes in PostgreSQL 10:
- The switch-xlog command has been renamed to switch-wal.
- In commands output, the xlog word has been changed to WAL and
location has been changed to LSN when appropriate.
- Add the --network-compression/--no-network-compression options to
barman recover to enable or disable network compression at run-time
- Add --target-immediate option to recover command, in order to exit
recovery when a consistent state is reached (end of the backup,
available from PostgreSQL 9.4)
- Show cluster state (master or standby) with barman status command
- Documentation improvements
- Bug fixes:
- Fix high memory usage with parallel_jobs > 1 (#116)
- Better handling of errors using parallel copy (#114)
- Make barman diagnose more robust with system exceptions
- Let archive-wal ignore files with .tmp extension
Version 2.2 - 17 Jul 2017
- Implement parallel copy for backup/recovery through the
parallel_jobs global/server option to be overridden by the --jobs or
-j runtime option for the backup and recover command. Parallel
backup is available only for the rsync copy method. By default, it
is set to 1 (for behaviour compatibility with previous versions).
- Support custom WAL size for PostgreSQL 8.4 and newer. At backup
time, Barman retrieves from PostgreSQL wal_segment_size and
wal_block_size values and computes the necessary calculations.
- Improve check command to ensure that incoming directory is empty
when archiver=off, and streaming directory is empty when
streaming_archiver=off (#80).
- Add external_configuration to backup_options so that users can
instruct Barman to ignore backup of configuration files when they
are not inside PGDATA (default for Debian/Ubuntu installations). In
this case, Barman does not display a warning anymore.
- Add --get-wal and --no-get-wal options to barman recover
- Add max_incoming_wals_queue global/server option for the check
command so that a non blocking error is returned in case incoming
WAL directories for both archiver and the streaming_archiver contain
more files than the specified value.
- Documentation improvements
- File format changes:
- The format of backup.info file has changed. For this reason a
backup taken with Barman 2.2 cannot be read by a previous
version of Barman. But, backups taken by previous versions can
be read by Barman 2.2.
- Minor bug fixes:
- Allow replication-status to work against a standby
- Close any PostgreSQL connection before starting pg_basebackup
(#104, #108)
- Safely handle paths containing special characters
- Archive .partial files after promotion of streaming source
- Recursively create directories during recovery (SF#44)
- Improve xlog.db locking (#99)
- Remove tablespace_map file during recover (#95)
- Reconnect to PostgreSQL if connection drops (SF#82)
Version 2.1 - 5 Jan 2017
- Add --archive and --archive-timeout options to switch-xlog command
- Preliminary support for PostgreSQL 10 (#73)
- Minor additions:
- Add last archived WAL info to diagnose output
- Add start time and execution time to the output of delete
command
- Minor bug fixes:
- Return failure for get-wal command on inactive server
- Make streaming_archiver_names and streaming_backup_name options
global (#57)
- Fix rsync failures due to files truncated during transfer (#64)
- Correctly handle compressed history files (#66)
- Avoid de-referencing symlinks in pg_tblspc when preparing
recovery (#55)
- Fix comparison of last archiving failure (#40, #58)
- Avoid failing recovery if postgresql.conf is not writable (#68)
- Fix output of replication-status command (#56)
- Exclude files from backups like pg_basebackup (#65, #72)
- Exclude directories from other Postgres versions while copying
tablespaces (#74)
- Make retry hook script options global
Version 2.0 - 27 Sep 2016
- Support for pg_basebackup and base backups over the PostgreSQL
streaming replication protocol with backup_method=postgres
(PostgreSQL 9.1 or higher required)
- Support for physical replication slots through the slot_name
configuration option as well as the --create-slot and --drop-slot
options for the receive-wal command (PostgreSQL 9.4 or higher
required). When slot_name is specified and streaming_archiver is
enabled, receive-wal transparently integrates with pg_receivexlog,
and check makes sure that slots exist and are actively used
- Support for the new backup API introduced in PostgreSQL 9.6, which
transparently enables concurrent backups and backups from standby
servers using the standard rsync method of backup. Concurrent backup
was only possible for PostgreSQL 9.2 to 9.5 versions through the
pgespresso extension. The new backup API will make pgespresso
redundant in the future
- If properly configured, Barman can function as a synchronous standby
in terms of WAL streaming. By properly setting the
streaming_archiver_name in the synchronous_standby_names priority
list on the master, and enabling replication slot support, the
receive-wal command can now be part of a PostgreSQL synchronous
replication cluster, bringing RPO=0 (PostgreSQL 9.5.5 or
higher required)
- Introduce barman-wal-restore, a standard and robust script written
in Python that can be used as restore_command in recovery.conf files
of any standby server of a cluster. It supports remote parallel
fetching of WAL files by efficiently invoking get-wal through SSH.
Currently available as a separate project called barman-cli. The
barman-cli package is required for remote recovery when get-wal is
listed in recovery_options
- Control the maximum execution time of the check command through the
check_timeout global/server configuration option (30 seconds
by default)
- Limit the number of WAL segments that are processed by an
archive-wal run, through the archiver_batch_size and
streaming_archiver_batch_size global/server options which control
archiving of WAL segments coming from, respectively, the standard
archiver and receive-wal
- Removed locking of the XLOG database during check operations
- The show-backup command is now aware of timelines and properly
displays which timelines can be used as recovery targets for a given
base backup. Internally, Barman is now capable of parsing .history
files
- Improved the logic behind the retry mechanism when copy operations
experience problems. This involves backup (rsync and postgres) as
well as remote recovery (rsync)
- Code refactoring involving remote command and physical copy
interfaces
- Bug fixes:
- Correctly handle .history files from streaming
- Fix replication-status on PostgreSQL 9.1
- Fix replication-status when sent and write locations are not
available
- Fix misleading message on pg_receivexlog termination
Version 1.6.1 - 23 May 2016
- Add --peek option to get-wal command to discover existing WAL files
from the Barman's archive
- Add replication-status command for monitoring the status of any
streaming replication clients connected to the PostgreSQL server.
The --target option allows users to limit the request to only hot
standby servers or WAL streaming clients
- Add the switch-xlog command to request a switch of a WAL file to the
PostgreSQL server. Through the '--force' it issues a CHECKPOINT
beforehand
- Add streaming_archiver_name option, which sets a proper
application_name to pg_receivexlog when streaming_archiver is
enabled (only for PostgreSQL 9.3 and above)
- Check for _superuser_ privileges with PostgreSQL's standard
connections (#30)
- Check the WAL archive is never empty
- Check for 'backup_label' on the master when server is down
- Improve barman-wal-restore contrib script
- Bug fixes:
- Treat the "failed backups" check as non-fatal
- Rename '-x' option for get-wal as '-z'
- Add archive_mode=always support for PostgreSQL 9.5 (#32)
- Properly close PostgreSQL connections when necessary
- Fix receive-wal for pg_receive_xlog version 9.2
Version 1.6.0 - 29 Feb 2016
- Support for streaming replication connection through the
streaming_conninfo server option
- Support for the streaming_archiver option that allows Barman to
receive WAL files through PostgreSQL's native streaming protocol.
When set to 'on', it relies on pg_receivexlog to receive WAL data,
reducing Recovery Point Objective. Currently, WAL streaming is an
additional feature (standard log archiving is still required)
- Implement the receive-wal command that, when streaming_archiver is
on, wraps pg_receivexlog for WAL streaming. Add --stop option to
stop receiving WAL files via streaming protocol. Add --reset option
to reset the streaming status and restart from the current xlog
in Postgres.
- Automatic management (startup and stop) of receive-wal command via
cron command
- Support for the path_prefix configuration option
- Introduction of the archiver option (currently fixed to on) which
enables continuous WAL archiving for a specific server, through log
shipping via PostgreSQL's archive_command
- Support for streaming_wals_directory and errors_directory options
- Management of WAL duplicates in archive-wal command and integration
with check command
- Verify if pg_receivexlog is running in check command when
streaming_archiver is enabled
- Verify if failed backups are present in check command
- Accept compressed WAL files in incoming directory
- Add support for the pigz compressor (thanks to Stefano Zacchiroli
zack@upsilon.cc)
- Implement pygzip and pybzip2 compressors (based on an initial idea
of Christoph Moench-Tegeder christoph@2ndquadrant.de)
- Creation of an implicit restore point at the end of a backup
- Current size of the PostgreSQL data files in barman status
- Permit archive_mode=always for PostgreSQL 9.5 servers (thanks to
Christoph Moench-Tegeder christoph@2ndquadrant.de)
- Complete refactoring of the code responsible for connecting to
PostgreSQL
- Improve messaging of cron command regarding sub-processes
- Native support for Python >= 3.3
- Changes of behaviour:
- Stop trashing WAL files during archive-wal (commit:e3a1d16)
- Bug fixes:
- Atomic WAL file archiving (#9 and #12)
- Propagate "-c" option to any Barman subprocess (#19)
- Fix management of backup ID during backup deletion (#22)
- Improve archive-wal robustness and log messages (#24)
- Improve error handling in case of missing parameters
Version 1.5.1 - 16 Nov 2015
- Add support for the 'archive-wal' command which performs WAL
maintenance operations on a given server
- Add support for "per-server" concurrency of the 'cron' command
- Improved management of xlog.db errors

- Bug fixes:
- Avoid retention policy checks during the recovery
- Avoid 'wal_level' check on PostgreSQL version < 9.0 (#3)
- Fix backup size calculation (#5)
Version 1.5.0 - 28 Sep 2015
- Add support for the get-wal command which allows users to fetch any
WAL file from the archive of a specific server
- Add support for retry hook scripts, a special kind of hook scripts
that Barman tries to run until they succeed
- Add active configuration option for a server to temporarily disable
the server by setting it to False
- Add barman_lock_directory global option to change the location of
lock files (by default: 'barman_home')
- Execute the full suite of checks before starting a backup, and skip
it in case one or more checks fail
- Forbid to delete a running backup
- Analyse include directives of a PostgreSQL server during backup and
recover operations
- Add check for conflicting paths in the configuration of Barman, both
intra (by temporarily disabling a server) and inter-server (by
refusing any command, to any server).
- Add check for wal_level
- Add barman-wal-restore script to be used as restore_command on a
standby server, in conjunction with barman get-wal
- Implement a standard and consistent policy for error management
- Improved cache management of backups
- Improved management of configuration in unit tests
- Tutorial and man page sources have been converted to Markdown format
- Add code documentation through Sphinx
- Complete refactor of the code responsible for managing the backup
and the recover commands
- Changed internal directory structure of a backup
- Introduce copy_method option (currently fixed to rsync)
- Bug fixes:
- Manage options without '=' in PostgreSQL configuration files
- Preserve Timeline history files (Fixes: #70)
